I have a question regarding a particular photo which appears to have multiple light sources even though the Sun is the only light source. If anyone could explain this that would be great or put forth theories.
The following instructions:

Put into Photoshop, Adobe Fireworks or any program that lets you turn the picture into negative
Put into negative ( this is to get better detail of the shadows)
Start from the position of the Astronaut, all shadows should be parallel as they originate from the same light source. Go to the left of the Human shadow and notice the shadows of the rocks point inwards. Then go to the right of the Human shadow and again, they point inwards. Then look at the ELM(Vehicle) and the shadow is not parallel at all.
